4 Claims. `l This invention relates to improvements in agricultural implements, and more particularly to a cotton chopper and cultivator.

An object of the invention is to provide an improved cotton chopper and cultivator adapted to be secured to a tractor or tractordrawn cultiwheel and soil loosener and grass picker wheels as the device is drawn along the rows of cotton.

Another object of the invention is to provide an improved cotton chopper and cultivatorvattachment which may be secured to a tractor or a tractor drawn cultivator, whereby cotton may be blocked out,v cleaned of grass, the soil of the row loosened, and the cotton dirted up in one operation.

A further object of the invention is to provide an improved cotton chopper and cultivator which will be highly e'icient in operation, and relatively inexpensive to manufacture and produce.

Other Iobjects will appear as the description proceeds.

In the accompanying drawings which form a part of this application,

Figure 1 is a front elevation of the improved cotton chopper and cultivator;

Figure 2 is a front elevation of the improved cotton chopper and cultivator showing the same attached to a cultivator frame of a tractor;

Figure 3 is a side elevation of the improved cotton chopper and cultivator;

Figure 4 is a side elevation of the improved cotton chopper andcultivator shown attached to the main tractor cultivator frame;

Figure 5 is a plan view of the improved cotton chopper and cultivator with part of the frame Vand gear box broken away, and

Figure 6l is a view taken on the line 6 3 of Figure l, showing the stub axle for the ground wheel in section.

Like characters of reference `are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided an improved cotton chopper and cultivator including a U-frame made from angle iron and having a back member I connected to the forwardly extending side arms 2 and 3 by means of the bolts or screws 4, said frame being reinforced by the connecting webs 5 at the juncture points between the ends of the back member I and the attached side members 2 and 3.

A depending bracket arm 5U is formed with the spaced slots 6 and is secured to the side member 3 by meansof bolts 'I extending through the slots in the arm and the adjacent side member 3, and supports an inwardly directed rotatable stub shaft 8 on its lower extremity, whereby the shaft 3 may be adjusted vertically with respect to the ground as desired. f

A ground'engaging wheel 9 is secured to the stub shaft 8, and a. sprocket I 0 is xed to the inner end of the -shaft 8 to rotate with said wheel 9.

A depending square supporting standard II is secured to the side member 2, and is adapted to support the gear box I2 for vertical' adjustment thereon, and to be secured in the desired position by means of the standard engaging set screw I3 extending through the said gear box. The shaft I is mounted transverselyof the gear box I2 in the bearings I5 and I6, and extends a considerable distance outwardly from the sides of the said gear box. v

The hub membersI'l and I8 are secured to the shaft III to rotate therewith, and support the plurality of wire spring fingers I9 having bent terminal ends 20, which are adapted to loosen the dirt along the rows of cotton and to take the grass therefrom.`

A sprocket 2| is fixed tothe end of the shaft IIS adjacent the ground `wheel 9, and is adapted to be aligned with the sprocket` I0 on the stub shaft 8 and to be connected thereto by means of the sprocket chain 22.,

A shaft 23 is rotatably supported by the gear box I2 in a suitable bearing 24, and supports the bevel gear 25 on its inner endl which intermeshes with the bevel gear 26 on the cross shaft I4. A head 2l is secured to the forward end of the shaft 23, and isadapted to support the outwardl7 extending rods 28 on the end of which the chopping hoes '29 are mounted for use in blocking out the cotton. Set screws 30 will extend through the head 21 to lock the rod 28 and hoes 29 in assembled position.

If desired, a hub similar to the hub members I'I and I8 with spring fingers I 9 may be substituted on the end of the shaft 23 for the chopper, to take out the grass by running across the row.

The hinges 3l will be secured to the opposite ends of the cross or back member I of the U-frame and to the depending arms 32 of the chopper supporting frame, to permit the U-frame with the ground wheel and associated mechanism to rise and fall as the wheel follows the uneven contour of the ground.

Clamps 34 will be positioned at the upper ends 3 of the chopper supporting arms 32 and will connect to the laterally extending cultivator frame 35 of the tractor on the main tractor cultivator frame 38.

From the foregoing description, it will be apparent that there has been provided a highly eiicient cotton chopper and cultivator which will perform the multiple operations of blocking out the cotton, cleaningthe `,grass therefrom, ,loosening thesoil in'tlre rowsand dirting up theftrows in one operation.

The preferred embodiment of the invention has been illustrated and described, but it will be understood that it is not intended `ttolimit ithe scope of the invention thereto, as ,many vminor changes in detail of construction maybe'resortetl to without departure from the sspirit -zof Lt'he invention.
